Kelas 8 MatematikaBab Persamaan Garis
y = mx + c
m = gradien
3y = -6x + 9
3y/3 = (-6x + 9)/3
y = -2x + 3
Gradien = -2

Materi : Persamaan GarisKelas : VIII
Tentukan gradien dri persamaan garis 3y = 9 - 6x, yaitu ?
→ 3y = 9 - 6x
= y = 9 - 6x / 3
= y = 3 - 2x
→ Rumus gradien adalah y = mx + c
= y = mx + c → y = - 2x + 3
✓ Sehingga dengan mudah di dapat nilai gradien (m) = - 2
Semoga membantu...
